Referring to the drawings in detail. designates the tinning pot. whieli is of a proper width to receive two sets of upper (inning rolls 10 and 11 respective ji'. while. above and in line with eaeh upper net. of tinning,r rolls is a set of feed-mt rolls 13 and 13 respectively. eaeh being 0i any approved type.

Be-

tween the opponite "relies extend rross bars 17 to whieh are seruied inrlined guide ugers 1S and 15". The. space between the guide lingers hv reaon of the dirapnaitixn. thereoi. tapers upwardljiv and direi-ts the upper end of the rin-ing sheet into the-nip of the feedout. rolls,

Above and between the two sets of lower feeitout rolls is a single lip-per set of feedout rolls` earn eoniprisingr a huh 2U. spokes Q1 and a rini l2 which are integral with eaeh other. 'lfhe sheets are `guided from eaeh side into thi l upper or single pair otl feed-out rollb hv the outer guide fingers 235 which are bolted to eromk hars 2T on the. )'niies. while the. uhulai guide i3 is nmunted between the in an)- suitable manner` The sheets. ruin;r troni the upper fiwdnut. rolls 5 up iwf neen inclined guides; iti halted or rune aeeured lo the. uiiperram; yultes,

After each sheet is thus fed upwardly between the guides it slides back 4from the feed-out rolls and down the inclined chute 27.

As the upper single pair of feed-out rollers handles the product from both lower pairs of feed-Out rollers it is desirable that this upper pair should be driven at a higher rate of speed than the lower pair and there are provided suitable connections for so driving the upper rollers at higher speed, and these connections are made with a shaft 28 which supports the upper single paii: of feed-out rollers which are mounted upolrlthe shaft in a manner presently described'. f The hub 20 of each upper pair of feedlout rollers is loosely engaged upon the shaft 28, while fixed to the latter at opposite sides of the hub and spaced therefrom are collars 29 which have mounted therein eccentrically disposed pins 30 to each of whichis connected one end of a coiled tensioning spring 31, the same surrounding a sleeve 32 loose upon the shaft 28 between the hub 20 and the collar 29 adjacent thereto, while the opposite end of the spring 31 is connected to a pin33 mounted eccentrically in each upper fed- 'out roller preferably in one spoke 21 thereof. Each collar 29 is flxed upon the Shaft 28 through the medium of a set screw 34.

Fastened on either side of each uppermost feed-out roller is a ratchet toothed rimr35, while pivoted to the cross bar 24 supporting the fingers 23 is a ratchet pawl 36, the latter 35being adapted to engage the ratchet rim 35 so as to prevent recoil of the springs 31 on the slackening thereof when the plate has been jerked. -4 from the lower feed-out roll under thetensloning of the spring 31 connected to the uppermost feed-out roll.

Passed between a pair of the spokes 21 adjacent each other is an upwardly arched bar 37 which is also fastened to the set screws 34 and this bar serves to act as a safety device to allow a certain amount of tension of the springs coacting with the upper set of feed-out rolls.

In Figs. 5, (i and 7 there is shown a slight modification of the invention wherein each uppermost feed-out roll comprises a wheel body 38 having a hub portion 39 for loosely surrounding the shaft 40 to which is fixed a collar 41 which holds the feed-out roller against longitudinal displacement, in`one direction, on the shaft, while lixed'to the sl ft at the opposite side of the wheel body y38 is a disk 42 having mounted therein eccentrically of the same a pin 43 which works within a slot 44 formed in the wheel body 38, and to this pin is connected one end of a coiled tensioning spring 45 which is housed within the wheel body 138 and has its opposite end fixed to a pin 46 mounted eccentrically on the wheel body. Bolted or otherwise secured exteriorly to'one side of 6 the wheel body 38 is a ratchet toothed rim 47 with which is adapted to engage a ratchet pawl, the same being the equivalent of the pawl 36 hereidbefore described and is mounted in a manner identical thereto so as to avoid any recoil of the spring 45' when tension is relieved therefrom.

When the sheets are taken in by the upper single set of feed rollers the springs acted upon by the shaft become tensioned by reason of the fact that the shaft is driven at a. faster rate of speed than the roller and when the sheets ride off ofthe lower feed` out rollers these upper feed-out rollers which are now tensioned will suddenly jerk the sheets from the lower feed-out rollers, thereby avoiding the dragging of the sheets or the marking of the same by reason of a drag. or other injury to the sheets, because, due to the mounting of the upper feed-out rollers, the same are free to move slower than the speed of rotation of the shafts supporting," them as the springs take up the increased speed of the latter by the tensioning of the, springs, and when the sheets are about to run from the other rollers, due to the tensioned condition of the springs, the upper* feed-out rollers Iwill jerk .the sheets therefrom, thus avoiding injury to the sheets resultant from the dragging thereof.

From the foregoing descriptionrtaken in connection with the accompanyin drawings, the construction and operation o the herein described device will be readily vapparent and, therefore, a more extended explanation has been omitted'.

Having thus described my invention, I claim:

1. A catcher roll for tin plate catchers comprising a wheel like body adapted to be loosely mounted upon one of the shafts of y the catcher, a ratchet wheel exteriorly of the body and movable therewith, a station arily mounted pawl engageable with the ratchet gear, a collar adapted to be fixed to said shaft, and tensioning means connected .with the wheel body and the said collar.

2.` A catcher roll for tin plate catchers comprising a wheel like body adapted to be loosely mounted upon one of the shafts of the catcher, a ratchet wheel exteriorly of the body and movable therewith, a stationarily mounted pawl engageable with the ratchet gear, a collar adapted to be fixed to said shaft, tensioning means connected with the wheel body and the said colla and means for limiting free movement or the connection between the wheel body and the said .tensioning means.
